SpaceDaily

Orbiters, landers, balloons, aircraft, or penetrators similar to the ill-fated Deep Space 2 mission. Just about everything that could be carried on a Mars Micromission has been suggested in the aerospace media. There’s just one concept that doesn’t seem to have attracted much attention: the Mars Smart Bomb! The idea takes its inspiration from the graphic video footage beamed back from cameras in the noses of these guided weapons, providing steadily more detailed imagery of the ground as they sped towards their targets.
